Question

5.26×1.3+6×4.74+5.26×4.7的过程？

Answer 1

解:

原式

=(5.26x1.3+5.26x4.7)+4.74x6

=5.26x(1.3+4.7)+4.74x6

=5.26x6+4.74x6

=(5.26+4.74)x6

=10x6

=60

方法:

两次利用乘法分配律实现简便计算。

Answer 2

5.26×1.3+6×4.74+5.26×4.7
=5.26×(1.3+4.7)+6×4.74
=5.26×6+6×4.74
=6×(5.26+4.74)
=6×10
=60
分析:本题可以按正常计算，同样也可以简便计算。正常计算，就是把三个陈华顺数全部先相乘，最后再相加。简便计算，就是观察先后出现5.26和6,两次运用乘法分配来计算。

Answer 3

简便运算
5.26×1.3+6×4.74+5.26×4.7
= 5.26×1.3+5.26×4.7+6×4.74
= 5.26×(1.3+4.7)+6×4.74
= 5.26×6+6×4.74
= 6×(5.26+4.74)
= 6×10
= 60

Answer 4

解：原式=5.26×（1.3+4.7）+6×4.74
=5.26×6+6×4.74
=6×（5.26+4.74）
=6×10
=60

Answer 5

原式=5.26×（1.3+4.7）+6×4.74
=5.26×6+6×4.74
=6×（5.26+4.74）
=6×10
=60
